  11. Winter Sea Ice Trends

  12. take home messages Arctic sea ice - is melting - is melting fast - will impact the globe

  13. Atmosphere

  14. Global Mean Temperature Temperature (°C) data source: NASA Goddard Institute

  15. Global Mean Temperature Temperature (°C) 130 year trend +0.06 °C / decade data source: NASA Goddard Institute

  16. Global Mean Temperature Temperature (°C) 50 year trend +0.15 °C / decade data source: NASA Goddard Institute

  17. Global Mean Temperature Temperature (°C) 20 year trend +0.20 °C / decade data source: NASA Goddard Institute

  18. New Energy Storage Atmosphere 3% Soil 4% Ice 8% Ocean 85%

  19. take home messages Climate change - is here - is significant - more change is expected

  20. What is the cause of climate change?

  21. 27

  22. 28

  23. 29

  24. Carbon Dioxide Modern Data 30

  25. 31

  26. take home messages Climate change • is caused by the burning of fossil fuels • we are all responsible • we need to shift the energy economy

  27. Energy Economy

  28. World Oil Prices source: US Energy Information Administration $ per barrel

  29. World Oil Prices source: US Energy Information Administration $ per barrel

  30. World Oil Prices source: US Energy Information Administration $ per barrel

  31. Rough Energy Statistics Oil Coal Natural Gas Nuclear Renewables Global Mix 35% 30% 20% 5% 10% Cost/ kWh $.05 $.04 $.04 $.10 - .20 $.04 - .06 $.08 $.30 +$50CO2 Tax $.06 ($.07) $.06 $.05 $.10 - .20 $.04 - .06 $.08 $.30 Oil (Bitumen) Coal Natural Gas Nuclear Hydro Wind Solar (PV)

  32. sector end use gas Global GHG emissions by sector source: World Resource Institute CAIT source: from 2000 including land use (CO2eq)

  33. Canadian Emissions source: Stats Canada

  34. take home messages Energy economy • cost of fossil fuels is rising • emissions are rising • we need to shift the energy economy

  35. Moving forward
